"Soul Master is a general term for soul masters who practice in the main direction of researching, manufacturing, and using soul guides. Xiao Huadong, you should know, right? Lin Ruoxi asked.

Dai Huadong was a little weak: "Teacher...... No...... Forget it, you can't change it anyway, teacher, can you show me how they study soul guides? ”

Today's study of the Martial Soul Department has ended, and Huo Yuhao is going to study in the Soul Guide Department again, so Dai Huadong came to Lin Ruoxi and asked her to take her to visit the Soul Guide Department.

"This one...... It's bad to bother others with research, right? Lin Ruoxi said.

Dai Huadong thought for a moment and said, "Then Mr. Lin, how did you do your research?" You're also a teacher of the Soul Guide Department, right? ”

"It's usually about studying how to maximize the power of the core circle, and then it's about designing some new circles." Lin Ruoxi said, "But progress is slow, after all, it is not so easy to develop the latest available core circle. The Soul Guide Department mainly teaches students how to engrave the core circle and create a soul guide. ”

"As I said before, this is simply the work of a craftsman, no wonder the soul guide develops so slowly." Dai Huadong supported his forehead, like the academy in his previous life, he taught theory first, and as for practical ability, he could naturally learn it in his work.

Lin Ruoxi didn't hear Dai Huadong's words, she said: "Xiao Huadong, if you are interested in soul guides, I can teach you, I am also a seventh-level soul master." ”

"Okay, then please Mr. Lin." Dai Huadong nodded.

And then......

"I'm so tired!" Dai Huadong felt that his hands were numb, he had been playing iron for a long time under the supervision of Lin Ruoxi, and his hands were almost numb.

"I can't give up, since I've decided to do it, I must do it to the end." Lin Ruoxi encouraged.

Listening to Lin Ruoxi's voice that could make people's ears pregnant, Dai Huadong suddenly felt that his heart had been healed, but although his consciousness had subjective initiative, in the end, he still couldn't change the fact that Dai Huadong couldn't even lift his hand. But Lin Ruoxi was still staring.

……

"So that's why your hands are shaking like crazy?" The outlying island looked at Dai Huadong's hands, "And it's blistering." ”

Dai Huadong said angrily: "I call this experience life." ”

"Huh."

"Yuhao, don't stop me! I'm going to fight her! ”

Huo Yuhao said helplessly: "Second brother, you have been pulling me ......"

Dai Huadong's old face turned red and roared: "What do you care about this!" And, what about the others? ”

"Wang Dong, they said they didn't understand at all, so they didn't come." Xiao Xiao said.

"Cut, okay, what's wrong with what I taught you yesterday?"

Huo Yuhao immediately asked: "Second brother, I tried it when I went back yesterday, and found that when two iron balls of different weight fell from the same height, they would land at the same time, why is this?" ”

"That's right! I've tried it too, but why did it land at the same time? Shouldn't it be heavy to land first? Xiao Xiao also showed a curious expression.

Dai Huadong stretched out a finger and said, "Since this is the case, then I will teach you the three laws of mechanics." Originally, Dai Huadong wanted to call it Newton's Three Laws, but no one in this world knew him, and Dai Huadong was embarrassed to hang his name, so it was called the Three Laws of Mechanics.

"The Three Laws of Mechanics?" Huo Yuhao muttered.

"The first law states that an object will remain at rest forever or move in a straight line at a uniform speed without being subjected to an external force."

"The second law, the acceleration of an object, is directly proportional to the force it exerts and inversely proportional to its mass."

"The third law, when an object exerts a force on the second object, the second object will also exert a force on the first object, and these two forces are equal in magnitude and opposite in direction."

"These three sentences include almost all the laws of the macrocosm, and most of the phenomena you can see cannot be separated from these three laws."

Huo Yuhao frowned and said, "But second brother, according to your first law, then why does the rolling stone stop even if no one touches it?" ”

Dai Huadong smiled: "Yuhao, you are right, why did it stop?" Because the ground gives it a frictional force, it will eventually stop. ”

"What is friction?" Xiao Xiao asked.

"The force that moves in the opposite direction of the object's movement trend is collectively called frictional force, but this distinction is not accurate, but I don't know the exact description, so let's just count it like this." Dai Huadong said.

"Is it really good to describe it casually?" The outlying island said lightly.

Dai Huadong glanced at her: "I'm just a high school student, it's not bad to be able to describe it to this extent." Why don't you come? ”

"Oh, you're busy."

“……”

After answering questions such as why it hurts to hit people in the face with their fists, what is the acceleration, and what is the mass, Dai Huadong introduced them to the concepts of gravitational force and gravitational acceleration. Finally, Dai Huadong said: "Back to the original question, why do two iron balls of different weights land at the same time, because their gravitational acceleration is the same, and the initial velocity is zero, so the time taken to travel the same distance is naturally the same." ”

"I see, I didn't expect this principle." Huo Yuhao said.

"But what's the use of that? Whether it's the soul guide system or the martial soul department, I don't feel like I need these. Xiao Xiao said.

Dai Huadong was silent for a while, and said: "Maybe the martial soul system can't be used, but for the soul guide system, this will be the theory that promotes the development of the entire soul guide system." ”

However, seeing the suspicion in Huo Yuhao and Xiao Xiao's eyes, Dai Huadong shook his head and said, "Forget it, let's go here today, you guys go back first." ”

Seeing the two leaving, Lidao said, "Why are you teaching them this? They shouldn't be able to understand the significance of these theories, right? ”

"Actually, I couldn't understand the significance of these theories at the beginning, because at that time I was still cursing why the durian that hit Newton's head was not the durian." Dai Huadong looked at Poseidon Lake, "However, since you have crossed over and you haven't hung up, you have to get something out, otherwise how can you be worthy of the identity of the traverser." ”

"You humans think strangely." Outlying islands gave a rating.

Dai Huadong looked at her: "You are completely similar to a human being." ”

"Without the support of the Deep Sea Fleet, it is foolish to be the enemy of the humans of this world at will, and the deep sea, although crazy, is not stupid...... At least not all of them. Outlying Island said.

"There seems to be a very suspicious pause in your words."

"No Road Race!"

"Your prototype is the land base of the US imperialists, right? Why neon language? ”

"No road race, no road race, no road race!"

“……”

In short, in the next few days, Dai Huadong got up every morning, went to class, and went to the soul guide department to learn the soul guide with Lin Ruoxi for a period of time after class in the afternoon, and then taught Huo Yuhao all kinds of miscellaneous knowledge of his previous life. Do some research in the evening.

The academy finally promulgated regulations on literary works, and at the same time, Shrek Publishing House was also established, and it is said that Vice President Qian Duoduo was desperate to take away the management rights of Shrek Publishing House.

Most of Dai Huadong's proposals were adopted, including a frighteningly high fine, piracy of other people's works without the authorization of the author and the publisher, and a fine of the specified market price * quantity * 2 if found to be imposed, and all pirated books will be confiscated, and if the selling price is higher than the specified market price, it will be calculated according to the selling price, and at the same time, if the number of sales cannot be queried, all their property will be confiscated. Of course, the specific operation will be very strict, and the decision to confiscate property will not be issued casually.

This suggestion is full of Dai Huadong's malice, and he can copy it openly...... Borrowing from the works of the previous life, you pathetic fellows can only risk breaking the bank to pirate, although it is unlikely that anyone will continue to pirate under such a severe fine.

However, Dai Huadong didn't know the news yet, and he hated this world where iron had to be struck by hand to remove impurities, so he decided that it was time to use a new purification technique! How can a traverser not order a tech tree?
